9. (extra credit) In a 300-person focus group, 60% of participants like durian. It turns out that people who like durian complete durian-related surveys with probability of 0.6, while people who do not like durian complete those surveys with probability of 0.8. Assume that these probabilities are independent of everyone else. Estimate the probability that more people who do not like durian filled out the surveys than the people who like durian in the focus group
